THE ASTEROSEISMIC POTENTIAL OF <i>KEPLER</i> : FIRST RESULTS FOR SOLAR-TYPE STARS

Abstract

We present preliminary asteroseismic results from Kepler on three G-type\nstars. The observations, made at one-minute cadence during the first 33.5d of\nscience operations, reveal high signal-to-noise solar-like oscillation spectra\nin all three stars: About 20 modes of oscillation may be clearly distinguished\nin each star. We discuss the appearance of the oscillation spectra, use the\nfrequencies and frequency separations to provide first results on the radii,\nmasses and ages of the stars, and comment in the light of these results on\nprospects for inference on other solar-type stars that Kepler will observe.\n
